Ans1.
Overcurrent-
Overcurrent or excess current may be a scenario wherever a bigger than meant electrical phenomenon exists through a conductor, resulting in excessive generation of warmth, and also the risk of fireside or damage to instruments.
Overload-
An electrical overload happens once an excessive amount of current passes through electric wires. The wires heat and might soften, with the chance of beginning a fireplace.
short circuit-
A short circuit is solely a low resistance connections between the 2 conductors supply power to any circuit. This leads to excessive current flow within the power supply through the 'short,' and will even cause the ability supply to be destroyed.
Dead short-
A dead short occurs when electric circuit has zero resistance. this could result from the "hot" electrical feed coming back in-tuned with a metal object, sort of a metal receptacle or with the bottom or neutral wire. Your initial sign that you simply might have a dead short are going to be a tripped breaker.
Arcing fault-
An arcing fault is that the flow of current through the air between section conductors or section conductors and neutral or ground.
Circuit Breaker
A circuit breaker is a device that senses interrupts the abnormalities or fault current. it's a machine that disturbs the flow of high magnitude (fault) current and in additions it performance is like a switch.
Fuse-
Fuse is an electrical device works when its senses overload in circuit, it can stop current from flowing.
Trip free
Free to trip on the incidence of any condition (as an overload) that provision is created although the traditional operational lever or the control-switch closing contact is control within the closed position a trip-free breaker.
Solid material fuse
The solid-material power fuses are required when the limits of the fused cutouts and fuse links have been exceeded due to higher fault currents or higher loads
